Santosh must sell the remaining dotpens with a surplus of 40 % to gain 10 % on the whole.

We know that Santosh sold 200 dotpens with a loss of 5 % and he must sell the remaining dotpens with an unknown surplus in order to obtain 10 % of the whole. The situation can be represented by the following expression:

[tex]-0.05\cdot (\frac{4500}{300} )\cdot (200) + x\cdot \left(\frac{4500}{300} \right)\cdot (100) = 0.10\cdot (4500)[/tex]  (1)

[tex]-150+1500\cdot x =450[/tex]

Step-by-step explanation:

Using proportions, it is found that her satellite bill before the switch was of $240.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, she can pay a total of $180 per 300 channels, hence her price per channel will be of:

p = 180/300 = $0.6.

She currently pays $0.2 more, that is, $0.8, hence:

B = 300 x 0.8 = 240.

Her satellite bill before the switch was of $240.

Answer:

The choice C .

[tex]1 \frac{17}{60} [/tex]

Step-by-step explanation:

[tex]q - \frac{6}{5} = \frac{1}{12} \\ \\ q = \frac{1}{12} + \frac{6}{5} \\ \\ q= \frac{5}{60} + \frac{72}{60} = \frac{77}{60} = 1 \frac{17}{60} [/tex]

Answer:

q = 1 [tex]\frac{17}{60}[/tex]

Step-by-step explanation:

q - [tex]\frac{6}{5} = \frac{1}{12}[/tex]

Add [tex]\frac{6}{5}[/tex]  to both sides.

q = [tex]\frac{1}{12} + \frac{6}{5}[/tex]

The least common multiple of 12 and 5 is 60. Convert [tex]\frac{1}{12}[/tex] and [tex]\frac{6}{5}[/tex] to fractions with denominator 60.

q = [tex]\frac{5}{60} + \frac{72}{60}[/tex]

Since [tex]\frac{5}{60}[/tex] and [tex]\frac{72}{60}[/tex]  have the same denominator, add them by adding their numerators.

q = [tex]\frac{5 + 72}{60}[/tex]

Add 5 and 72 to get 77.

q = [tex]\frac{77}{60}[/tex]

Add the 1 and you get:

1 [tex]\frac{77}{60}[/tex]

I am not sure about this but try it.

Using it's concept, it is found that the independent variable is the number of hours worked.

A function has the following format: y = f(x).

In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.

That is, the input of the function is the independent variable and the output is the dependent variable.

In this problem, the input is the number of hours worked and the output is the salary, hence, the independent variable is the number of hours worked.
